SAW-GUIDING INSTRUMENT.

Specification of Letters Patent.

T; Bill whom, it may concern known that 1, ADOLPH in the county of LosAngeles alifornia, have invented new and useful Improvements in Saw-Guiding Instruments, of specification.

Los Ange saw guiding means an "particularly to a. meelia-n i'smfwhich is adapted to hold a saw for- =mitering purposes, or-for ripping work as desired.

It is an ob]ect of the-invention toc rovide' v be 18 "in which a segmental slot 19; is formed,

a saw guiding instrument which, y held or cla'mpedupon wor 7 pr upon atvork bench and which may be used as a miteri instrument or may be employed to guide a saw in vertical or tipped planes or in ip ping lumber in strips with parallel edges;

It is also an object of'the invention to;provide a saw guiding implement with inovable means for engagingthe saw and clamping means. for holding the said movable means at various angles with respect to the work or the material which is to befoper- Med 1. on-

In t e accompanying drawing forming a partof this specification, Figure 1 is an en elevation of the improved "saw' guiding mans, the side of the frame for guiding the shown. Fig. 2 is .a top -plan view of the instrument when .in position for mitering purposes. Fig. 3 is a top plan ofthe instrument as set for ripping purposes. Fig. 4' is a side elevation' of the implement, the saw guiding in position for makin across out. Fi 5 is an enlargeddetai sectional view ta en through the saw guiding'means' upon the line 5-5 of Fig. 1. Fig, 6 is a detail-sectional view taken upon the line 6 -6 of Fig.2. Fig. 7 is an enlarg'ed detail sectional view taken throu h theelam ing head employed forholding the saw gui in frame in its various os'itions.

The details and features of the invention' will now be more particularly described,

reference bein had toflthe said drawing, in which 10 in icates a base plate provided with-a side "flange plate 11, arranged at angles thereto and adapted to engage the:

edge of the material worked upon or the '.'.-'of a work bench as found desirable.

adjustable plate 12 of approximately the f the United States, residing at,

to the end 'of with' a. segmental slot 14; engaging a set which the following is. a screw 15 carried by the said'plate 10, by which the plate 12;.may be clamped in its This invention relate toimprovements inand are connected at Patented June 10,1913., Application filed February 14,1912. .Serial No. 677,613.

same size and shape as the said plate l0and' H. KOCH, a-

adapted in using the-implement for. certain purposes to. be fitted, over I The plate 12 isnpi voted" at one end as at 13 e plate Y10 and is formed various positions jwith respect to the plate 10. i

The outer 'end of the -plate 12 carries a clamping, head '16, which is held in position on said plate by means of a set screw 17 The said head is also providedwith a plate which engages a' set screw; carried by the plate 12. The plate' is preferably provided with .gl'aduations 21-so that-the head may be set at any desired. angle with respect to the plate 12" or the work.

The head 16 is provided with an elongated bearin at .22 in which is journaled a longitudina 1y extending shaft 23.- The shaft 23 plate 10 inorder to do miter is screw threaded at one end and a bar 24 is provided with a screw threaded openin which is screwed upon the end 25 of sai shaft 23 and is adapteli to tighten the shaft d i in position when it-is turned downwardly to the position shown in Figsr2, 3 and t where the said plate 10.

eat

it is held b a removable screw 26. A lock nut 27 is a so applied upon the end of the said shaft 23 outside the bar 24 forfurt-herbinding the parts in position and insuring the holding of the frame carried uponthe shaft 23 in vertical .osition.

The saw guiding rame employed is' made up of a longitudinal head 28, having bearings 29 and 30 at its ends adapted to fit upon the shaft 23. Standards 31 rise from the said longitudinal head to a suitable height their upper ends by a bar 32, which fits upon screw threaded reduced ends formed upon said standards. Thumb nuts 33 engaging said screw threaded reduced ends, clamp the bar 32 in 'tion. The frame thus formed is held against turning upon the shaft 23 by means of a set screw 34 which engages 8.1101011- gated groove or One of the journals'29 is provided with.

a flange 38 which bearsv against a correkerf 35 formed in the said .shaft 23. The said cross-head 28 is also desired position, the

spondingly shaped flange 39, formed upon the head 16. The said flanges are preferably provided with graduations as at 40 and 41 respectively whereby the angular position of the saw guiding frame with respect tothe head 16 may be adjusted and set. 'The frame for guiding the saw is thus carried by the shaft 23 which is supported at one end by the said head 16. YVhen the head and the saW guiding frame carried thereby, has been properly adjusted to'the' shaft is usually further "supported by means of-a cam 42, which -is pivoted at 43, upon the elongated head 28 and when turned downwardly will brace the said head with respect to the work.

The head 16 is prevented from turning with respect to the plate 18 by means of dowel pins 44 and 45 which are carried by said head and projectinto apertures. formed clearly shown in Fig. 7.

in said plate as frame is provided with an The saw guiding adjustable cross head 46 having end sockets 47, fitting snugly upon the-said standards 31 in Fig. 2. The

and yet so that they can be forced up and down. Pivoted upon the central portion of said head 46 is a saw guiding member 48,

the said guiding member being held by means of a pivot pin 49 projecting from the central portion of'said cross head 46. The

-saw guiding member is provided with an inner folded plate 50and outer strengtheningyokes 5-1, U shaped incross section as shown in Fig. 5. Ball bearings 52 and 53 are also provided in the said guiding member for engaging the opposite sides of the saw, to prevent any frictional contact between the saw and said guiding member. The .outerballs '53 are preferably adjustably held in position by set screws 54 clearly illustrated in Fig. 5. The formation of the guide is such that the saw may be drawn and forth within the same without yet be held at the proper angle with respect to the work, to accomplish the miteringor other operation thereon.

When; it is desired to miter material, the deviceis placed upon the edge of a work bench and preferably clamped thereto in any desired-manner and the saw frame is'setat the desired angle to the proper miter, the. set-screw 20 being back friction and tightened for clamping the said frame in position; When .uslng the device in this manner the-plate 12 'is 1i1sually clamped directly over and upon theplate 10 as shown sawfmoves; loosely in the guide for producing thedesired out. When Copies guide 11, along guiding produce of this patent may be obtained for live cents each, by addressing the inthis position also an inclined cut, tipped from a vertical position, may be made by,

turning the saw frame with the shaft 23 upon the head 16 as indicated in dotted lines in Fig. 4, thus a battle-or miter in a different planefrom that contemplated in the adjustment shown in Fig. 2 may be accomplished. When it is desired. to rip a piece oflurnber, the plate 12 is adjusted with respect to the plate 10. By movingthe plate 10 withut'he from point to point a continued and accurate ripping of the material can be accomplished.

What I claim is:

1. A saw guiding implement comprising 1 a lateral shaft carried by said segment plate and adjustably supported thereon and a saw guiding frame: carried by said-.'shaft.

3. A saw a guiding base plate, an adjustable plate pivoted thereon, a head pivotallyand-adjustably mounted on said latter plate, a lateral shaft carried by said head, a saw guide frame mounted on said shaft, and means for clamping the parts at various angles with respect to each other.

4. A saw a work engaging base, a plate pivoted thereto and adapted to be clamped at different...

guiding implement comprising.

guidingimplement comprising angles with respect to the same, a head also" pivoted tosaid plate and adapted to be clamped'at various angles with respect thereto,'a shaft carried'by the said head, 'a saw frame mounted thereon and adapted to be clamped in various a'vertical position thereon, and a pivoted saw engaging guide member carried by said frame. In witness that I claim the foregoing I have hereuntwsubscribed my name this th day of February, 1912.
